<h3>
    摘要
</h3>
<p>
    如果不加进一步限制，将 RUP 标注为重量级、将 XP
    标注为轻量级，会因为遮盖每个程序的内容和每个程序要执行的操作而造成危害。并且，以错误的方法执行时，只是无意义的摆设。这些进程的实施才需要区分“重量级”或“轻量级”，并且应该根据环境的要求确定是重量级还是轻量级。
</p>
<p>
    XP 不是空白表单，怎么做都可以，它专门侧重于软件开发的特定方面，是一种交付值的方法，并对完成该任务的方式有具体规定。&nbsp;
</p>
<p>
    RUP 的覆盖范围广，并且涉及内容深，这说明其外观“大小”。但在进程的微观级别，RUP 偶尔允许并提供同样有效的替代方法，而 XP 则不会；例如：XP 必须进行结对编程。这并不是批评 XP，只是说明 XP
    是如何（如其名称暗示的那样）缩小其侧重范围的。
